Analysis

Lead in Missouri: what the data shows

Missouri has 487 cities with lead monitoring data, with no cities exceeding the EPA action level of 15 ppb. The state average 90th percentile lead level is 1.8 ppb, compared to 3.3 ppb nationally — better than the national average. No cities in Missouri currently exceed the 15 ppb lead action level. However, even levels below the action level can pose health risks, particularly for infants and young children. If your home was built before 1986, consider testing your tap water directly. The 90th percentile measurement means that 90% of tap samples in a city are at or below the reported level. This is the standard EPA uses under the Lead and Copper Rule to determine if a water system needs to take corrective action. An NSF 53-certified pitcher or under-sink filter can effectively remove lead at the tap.

FAQ

Frequently asked questions about lead in Missouri

Is lead in Missouri tap water a concern?

Currently, no cities in Missouri exceed the 15 ppb EPA lead action level. The state average is 1.8 ppb. Even below the action level, lead poses health risks especially for children and pregnant women. If your home was built before 1986, consider testing your tap water directly.

How can I reduce lead exposure from Missouri tap water?

Use an NSF 53-certified water filter, which is specifically certified to reduce lead. Run your cold tap for 30 seconds before drinking or cooking, especially if water has been sitting in pipes for hours. Never use hot tap water for cooking or making baby formula, as heat increases lead leaching from pipes.

Which Missouri cities have the highest lead levels?

The cities with the highest 90th percentile lead levels in Missouri are: Mercer (13.7 ppb), Ferrelview (12.2 ppb), Caruthersville (11.4 ppb), Heber (11.0 ppb), Hillsboro (10.9 ppb). See the full ranked table above.
